ESU LOKSOUND DECODERS

LokSound L – Premium DCC and Sound in O Scale

Further information

 

The Brand New LokSound L V4.0 and LokSound L Select decoders are made to fill a huge void in the O scale DCC market. For years now many have been using a large scale non sound decoder for the motor and wasting an HO Scale DCC and Sound decoder to operate the sound as no High Amperage, High Quality sound decoder has been available that will fit comfortably into an O scale locomotive. The wait is finally over! The LokSound L V4.0 and LokSound L Select decoders will easily use the many respective ESU V4.0 and Select sound files already on the market as they are of course programmable with the famous ESU LokProgrammer hardware.

The LokSound L decoder is still a combination of driving decoder and sound module on one PCB. You can install it in nearly every loco in O scale locomotive with its dimensions of only 2 inches in length and 1 inch wide! Made to Plug and Play in to New Atlas (and others) O Scale Locomotives, the Decoders will also come with an interface board for hardwiring into whatever Brand Locomotive you have.

With a constant current of 3Amps continuous the decoder’s load control will power all current O scale locomotives whether having 1 or 2 motors with ease. The decoder’s hardware includes 9(!) function outputs, ability run 2 servos, and inputs for 3 hall sensors (commonly used for syncing Steam Chuffs). You can also add 2 speakers as there are 2 separate speaker outputs (one Channel). Additionally there is the ability to add an external volume control and external power pack. Add this to the powerful logic contained in the LokSound V4.0 and Select technology already on the market and this new decoder is a force to be reckoned with! Finally “O Scalers” will have the Power, Sound and Motor Control they need, in a package that will fit in their locomotives model train decoders dcc locksound digitrax

If necessary, you can add the Decoder Tester Extension to your Profi Decoder Tester V2.0: Plugged into the side of the Decoder Tester V2.0 it enables you to comfortably test all large scale decoders.

 

If you also have to deal with large scale LokSound XL or LokSound L decoders in your workshop, the Profi Decoder Tester Extension is just the right thing for you: You can plug on LokSound XL V4.0 decoders with multi-pin connectors as well as LokSound L V4.0 decoders directly and easily test them.

 

The extension module has multi-pin connectors for direct plug-on of the decoder types mentioned above. An LED monitor with 12 LEDs displays the status of all physical function outputs.

 

You may also plug on a second speaker or sensor inputs onto the multi-pin connector for quick and easy testing. Up to four servos may also be plugged on for direct testing.

 

Especially for the LokSound L V4.0, connecting pins for a smoke generator have also been added.

 

The Profi Decoder Tester Extension represents the perfect test and programming bench in conjunction with the Profi Decoder Tester V2.0, where you can test and program almost all (ESU) decoders quickly and easily.

“Full Throttle” Decoder Operation for Diesels

It is often challenging to make a scale model preform like it has the mass of a 260,000lb locomotive pulling 5,000 tons or more! Some of this can be done with BEMF - when the loco “feels” a load, it will automatically rev up to work harder to pull this actual load. But this is often a flawed method in modeling. Today, model train car wheels are so free rolling that they often do not simulate sufficient drag to replicate a typical prototype situation. Also, often we do not sufficiently weigh our cars to represent a scaled-down version of the prototype. One of the biggest problems with BEMF controlled load is due to the fact that in our modeling and operations we often “simulate” loads inside a closed car. The payload inside a prototype car can weigh as much as 100-tons more than the car itself. This is especially important at operating sessions. Empties in and Loads out or vice versa. There is no way for a decoder to know the proposed weight of the cars it is pulling. Our “car cards”, showing whether a car is loaded or empty, are seen only by the operator, not by our decoders!

To compensate for what the decoder cannot know, we have created Full Throttle decoder features! This series of new features includes “Drive Hold”, “Run 8”, “Coast”, improved “Dynamic Brakes” and a new “Independent Brake” feature.

Drive Hold:

This feature allows the modeler to easily simulate a loaded or empty train by adding a single “Drive Hold” function button. When the button is pressed, the motor will remain at a constant speed, while the sound can be controlled independently from the motion with the throttle knob!  This exciting, new feature gives the operator the ability to have his or her train crawl in notch 8 or coast at 50mph. Then, by releasing the Drive Hold function button you simply go back to throttle-controlled speed and motion. No more switching between manual notching and programming on the main to go back and forth. All of this can be done on the fly with hardly even thinking about it.

Run 8:

There are times when hauling a heavy train over rolling hills that you may wish to remain in notch 8 at any speed desired. You could have the train slow, as it climbs a steep grade and then speed up upon levelling out. The Run 8 feature will allow for exactly that. Simply press the button and the prime mover will increase RPMs from wherever you are, all the way up to Notch 8 and hold. Once the function button is pressed, the sound is disengaged from the speed. Using the throttle knob you can now speed up or slow down with the sound remaining constant, at full throttle.

Coast:

The opposite of “Run 8”. Often when coming to a stop, the throttle of a real locomotive is put into Idle and the engineer coasts to a stop. Another situation that occurs is that once a train is up to speed when operating over rolling terrain, the engineer can coast to maintain a certain speed. By pressing the coast function button, the sound drops from wherever you are to idle and remains there. Once this function button is pressed, the sound is disengaged from the speed. Using the throttle knob, you can now speed up or slow down the train with the sound remaining constant, at idle.

Brake:

Along with Dynamic Brakes, a locomotive has an Independent Brake as well. This allows for the locomotive to stop more quickly than its regular momentum would normally carry it. LokSound Decoders now also have a working Independent Brake. This one is pretty self-explanatory – just press the brake and come to a stop! While this will work with whatever deceleration settings are in the loco, it tends to work more realistically if the loco has a large amount of deceleration. With these settings the loco will drift or coast much further when the brake is not applied. Then, by applying the brake, the loco will stop in a much shorter distance. As a note, you can now do standing brake tests by keeping the brake on and advancing the throttle knob so the sound of Notch 4 can be heard. In EMDs this is the point at which the Shaft-Driven compressor reaches its second stage, and pumps air faster through the train.

Dynamic Brake:

The ESU Dynamic Brake works like the prototype. Once applied, the sound will drop to idle. Then (once the electricity dissipates from the traction motors) the prime mover will rise depending on the prototype. Most EMDs rise to about notch 4. Other brands will vary. Once the prime mover comes up, the dynamic brake fans will be heard. During this time, a deceleration will be quicker since you “have your dynamic brakes on.” Once you release the button the fan will shut off as the prime mover drops again to idle. After a short delay the prime mover will once again come up to match the speed of your throttle - (other Full Throttle features may affect where your prime mover sound returns after the dynamic brake is turned off.) Please note, if you come to a stop when your dynamic brake is applied, the fan sound will cease and the prime mover will go down to Idle. You will need to turn it off before you begin to move or the cycle will start again. Prototype locomotive dynamics will not work while stopped.

The ESU Dynamic Brake has not really changed much with the new added features. But the new files will now work better when consisted together and using the Dynamic Brake. Also since not all locos have dynamics, you will now be able to set up your non-dynamic locos to work correctly with consisted locos using dynamic brakes. The ESU Dynamic Brake Logic Feature does increase the deceleration rate so please take this into account. If your loco does not have dynamic brakes you should still apply the “Dynamic Brake” LOGIC when consisting so that the engine slows with other dynamic brake-equipped locos in consist. If your loco is not equipped with dynamic brakes please choose Sound Slot 21 (Coast) for the sound on the dynamic brake function button. This will have your loco drop the prime mover sound to idle while the dynamic brake-equipped locos in the consist go through the dynamic brake cycles. You should not use the “Shift” logic with non-Dynamic brake locos. Doing so will result in the prime mover rising up to Notch 4. This is not correct for Non Dynamic Brake Locos in a consist. It needs to stay at idle.

Servo connection on LokSound L V4.0 / LoKSound Select L
The LokSound L V4.0 / LokSound Select L features two servo outputs: (Servo 3) should be function
mapped to Aux9. (Servo 4) should be function mapped to Aux10. All RC servos with positive impulse
signal can be used. We recommend to use “Digital” servos because these usually do not jitter during
startup. Before you can use the two servo outputs, you need to configure them as “Servo” in the
LokProgrammer software.

Smoke unit on LokSound L V4.0 / LokSound Select L
Both the LokSound L V4.0 / LokSound Select L can control a synchronized smoke unit. You need to use
a smoke unit that offers the following connections:
2x Fan motor
2x Heater
2x Temperature sensor
The decoder reads the data from the temperature sensor and controls the heater based on the desiredsettings,
so the smoke unit could never burn out. Please note that the settings for the smoke unit need
to be included in the sound project file. While you could easily change these settings on LokSound L
V4.0 decoders, the settings in LokSound Select L decoders could not be altered by yourself. ESU will
do the conversion of the LokSound Select files to be compatible with the Smoke units. Please try to
use smoke unit mechanisms that are offered by ESU as spare parts or equal parts that feature a temperature
sensor.
